摘要
针对直流断路器存在临界负载电流难灭弧的问题,对不同时间常数与临界负载电流的关系进行了分析。结合直流断路器相关标准,进行了临界负载电流测试试验。根据测试结果,总结了负载临界电流的变化规律,可供各相关人员参考。
It is hard to extinguish are in DC circuit breaker because of the existence of critical load current.Based on it,this paper analyzed the relationship between different time constant and critical load current.Combined with the relative standards,the paper carried out the test of critical load current.According to the test results,it sums up the change law of the critical current of the load which can provide reference for relative personnel.
